Review: Turn your doors Smart :) - Disclaimer: I have a lot of TAPO devices (I really mean a lot). Due to my work, I have a tendancy to move a lot. So changing alarm system on a regular basis can be a pain. And I stumbled onto TAPO a year ago (and changed houses during that year) and clearly, it's really easy to set up. I have 2 of these currently installed on doors, and they work really nicelly, instant notification on my phone when the door opens, when it stays open, when it closes. Simple to install into the app, really responsiv, it adds a nice layer of security to our house. As we moved houses last summer, I removed all of our TAPO products from our previous home and installed them in the new one. No issues to transfer and removing the T110 from their previous spots showed the high quality of the adhesive. They stayed in place nicelly and when removed, the adhesive was easy to clean off ! I recently bought the TAPO H500 directly from TP-Link and switched the T110 from the previous base to the H500 without any compatibility problem. Everything went smoothly. All in all, easy to install, reliable, cheap and long lasting !!
Review: Fab and works with home assistant. - I love Tapo smart sensors, there one of the best in the industry for ease of setup, integration, price point, reliability and design. I'd rate the T110 a 4.5, I use Tapo devices with the Tapo smart hub T100. whilst reliable the detection takes approx. 3.5 seconds - not sure if this is due to round trip latency or intentional battery life optimisation but certainly good enough for what I need it for. The 3M mounting stickers are at least in my opinion a bit on the thick side and would of preferred something half as thick for a tighter bond but ofc easily corrected. It works perfectly with home assistant using the TP-link integration. Recommended.

## Questions & Answers

**Q: If I put this inside on the ground floor looking out through a window, will it work to detect movement outside?**
A: No. PIR sensors will not work reliably through glass. Most likely not at all. The work in detecting changes in "Infra-red" heat energy.

They do however communicate to the hub over distance as they are not using wifi but 868Mhz radio communications.  I have the sensors fitted inside shipping containers and the radio transmission has no problem passing through the metal skin of the container. The sensor is there to detect the door opening.

You could fit outside in your garden but they are not waterproof so will need protection against the elements and not be in direct sunlight.  Ideal for alcoves.

**Q: Do these have a feature so if it doesn't see motion it can trigger lights to turn off?**
A: You can create a routine in the Alexa app, where if the Motion Sensor detects no motion for a certain length of time, it turns a device on/off (plug, bulb etc). I have mine set to turn my heater off if it detects no motion for 1 hour. So, if I forget to turn my heater off when I go out, it will do so after an hour of nobody being at home :-)

**Q: Hello, can I use the kasa hub with the tapo motion sensor and tapo smart switch? Thanks**
A: No, Kasa and Tapo are seperate apps and not compatible

**Q: Does this work with home assistant ?**
A: Yes the sensor works with the Tapo Hub and the home assistant app.

It's great to setup "Smart" automation routines.  Sensor detects something and then you add actions such as sound alarm turn on a light or record camera footage.

### ⭐⭐⭐⭐⭐ Solid Performance and Peace of Mind After a Year
*by M***. on 20 October 2025*

I’ve got two of these sensors fitted on the front and back door. After over a year of use, I’ve only just had a low battery warning on the front door, which is easily the busiest in the house. While the back one is still going strong, very impressed so far. The automation features through the Tapo app open up loads of possibilities. With kids constantly running in and out, it's great to get alerts when a door has been left open. It gives a real peace of mind knowing the house is secure and helps keep the heat in too. Additionally the alarm trigger for unauthorised entry works perfectly as well and can be set while away or set times i.e Late/AM. See video. One of my main concerns was whether the sensor would fit properly, as our doors aren’t completely flush. Thankfully, even with the gap as pictured (Claims to support 15mm), they still register open and close accurately. While I’m only using them on doors, they’d also be handy for checking that windows are closed while you are out if that's what you need. Pros: - Quick and easy to install/configure - Battery replacement is straightforward - Reliable detection - Affordable Cons: Needs a Tapo Hub to work, but on the plus side, the hub doubles as an alarm and supports plenty of other Tapo devices if you plan to expand your setup like I have.
